“International law, accepted as binding by Saudi Arabia, provides that capital punishment may only be imposed following trials that comply with the most stringent requirements of fair trial and due process, or could otherwise be considered an arbitrary execution,” they said.
“In light of reports that the trial against Mr al-Nimr fell short of such standards, we call upon the Saudi authorities to ensure a fair retrial of Ali Mohammed al-Nimr, and to immediately halt the scheduled execution,” the experts added.
Iran's supreme leader, Ayatollah Ali Khamenei, warned Saudi Arabia on Sunday of "divine revenge" over al-Nimr's death, while Riyadh accused Tehran of supporting "terrorism" in a war of words that threatened to escalate even as the U. He said Iran's "hostile policy" was aimed "at destabilizing the region's security," accusing Tehran of smuggling weapons and explosives and planting terrorist cells in the kingdom and other countries in the region.
He vowed that Saudi Arabia will not allow Iran "to undermine our security." "The history of Iran is full of negative and hostile interference in Arab countries, always accompanied with subversion, demolition and killing of innocent souls," al-Jubeir said, just before announcing the severing of diplomatic relations.
“Opposed to the death penalty in all cases and circumstances, we call for the execution to be called off.” A court rejected Mr al-Nimr’s final appeal this month at around the same time as Saudi Arabia was chosen to head up a key UN panel on human rights.
